NONTWISTING DEVICE FOR, TELEPHONE AND OTHER CORDS.

Application filed October 19, 1922.

To all whom it may concern:

t i. {O'Wll that l, JAB/{ES E. SmirsoN, a the United States, residing at569 s Avenue, in the borough of 'n, in the county of Kings and State ewYork, have invented certain new and improvements in Nontwisting DeforTelephone and Other Cords, of which the "following is a full, clear, andW erect specification.

'lhis *ention relates to means for pretelephone cords from twisting orbecoming in red, and my improvement is directed to the prod. :tion oi asimple device, 15 ad: to grip a telephone cord at two d points in itslength, to thus on the line thereof between objects, such as thereceiver and base, while causing the sire]; to be held, relatively toits extent,

lined loop which is incapable of twisting or becoming kinlre l.

The device is equally applicable to the cert length that extend. betweenthe transt d of a movable or desk telecl the. battery box.

the device, though primarily infor with telephone cords, is applicablewith other lengths of f thereof.

such cords are permanently seopposite ends to movable r immovable pointsor objects, also though the device is primarily intended for use withtelephone cords, it is equally applicable for use as a silent salesmanor advertising medium.

Briefly expressed my improved non-kink ing device for cords consists ofa piece of still material having means at separated points thereoti fortensionally gripping a cord of designated thickness, to therebyestablish a fixed loop comprising the slack or normally unusued portionof the cord length.

(Ether features and advantages of my invention will hereinafter appear.

In the drawing Figure 1 is a perspective view of the clevice in one ofits forms, as applied to a cord.

Fig. is a plan view of the device in a modified form thereof, with thegripping ends in lapped relation to the body portion of the device.

Fig. 8 is a side view of Fig. 2.

F lis a plan view of the device in the term ot a flat plate, withgripping tongues out theretron'i.

Fig. 5 is a section on the line 5-5 of F 4:.

F g. 6 is a plan view of the device, also l in the form of a flat plate,with its ends shaped to comprise gripping members, and

Fig. 7 is a section on the line 'Z-7 of Fig. 6.

In one form of my invention, as shown in Fig. 1, it may be composed ofstill wire, in a single lengtl'i, bent to provide the oppcsite folds 1.,2, and having outer length portions 3, 4 with an intermediate lengthportion 5, the outer length portions 1, 2, each being shaped near theirends into loops or :anrvatures 6, closed by reason of their terminalends tensionally abutting against the respective folds l and 2. The wirelength portions 3, iand 5 lie normally in adjacent parallelisii'i, sothat the loops 6, which are adapted to receive a cord such as atelephone cord, may tensionally clamp the cord against the lengthportion 5, respectively at opposite sides and ends thereof. It is bythus clamping a telephone cord at separated points along its length thata loop is formed in the cord which may comprise the normally unusedslacli' thereof, thereby preventing the cord from twisting and becomingkinl'ied.

Obviously the lengthof wire employed by me in producing this form of mydevice must be sufiiciently stout or stiff 'in its preformed shape toenable the length portions 3 and l to lie against length portion 5 undertension which is capable of gripping the telephone cord, at the loops 6,tightly enough to prevent slipping oi the cord; although the tenacity ofthe gripping pressure must not be too great to prevent the cord frombeing drawn manually through the loops for purposes of lengthwiseadjustment.

The tensional grip is so shaped and arranged that while it functionsproperly it can in no way injure the covering of the telephone cord. Onthe contrary, the use of the device materially lengthens the life ofboth the telephone wire and its covering, by preventing the twisting orkinking which otherwise would occur in normal use or" the receiver underthe present method of operation. 7

In a modified form of the wire device, shown in Figs. 2 and 3, the endloop portions 7 may normally lap over upon the folds 1 and 2, to"thereby enhance the tensional grip thereof.

It will be appreciated that in order to fit the device to the cord theloops 6 or '7 are to be manually spread open for the reception of thecord.

In another form of my invention shown .in Figs. 4 and 5 the device mayconsist of a flat strip of material 8, having spring tongues 9, 9, cuttherefrom at its opposite ends, these tongues 9, 9, being curved as at10, to comprise sockets for the reception of the cord, the tongues alsohaving their ends 11 outwardly flared to provide convenient means forthe entrance of the cord into the sockets.

In a still further modification, shown in Figs. 6 and 7, the strip offiat material 12 there represented has its opposite ends turned over,oppositely, toward the respective sides of the strip, in the form ofspring hooks 13, 13 to provide the cord engaging means which comprisethe essential feature of my invention.

Variations Within the spirit and scope of my invention are equallycomprehended by the foregoing disclosure.

I claim:-

Non-twisting means for slack length portions of cords comprising a pieceof stout spring wire folded into three parallel members lyingapproximately in the same plane, each of the outer members having itsand bent to co -act with an adjacent end of the central member, therebyforming a loop to receive and tensionally engage a cord.

Signed at the borough of Manhattan, in the city, county, and State ofNew York, this 16th day of October, 1922.
